Lithium Ion Batteries Manufacturer

Advantages and Disadvantages

Lithium battery NCM LFP
Energy density High, 240WH/kg Low, 140WH/kg
Low temperature resistance The lower limit is - 30 ℃ The lower limit is - 20 ℃
High temperature resistance Thermal runaway temperature is lower than 300 ℃ Be safer and thermal runaway temperature is more than 500 ℃
Cycle life(High end quality in the market) 2000 cycles and the service life is only 6 years 3500 cycles and the service life can reach to 10 years
Charging efficiency High Low
Manufacturing cost High Low
Environmental protection Poisonous No pollution, in line with European RoHS
Processability Good consistency and easy to assemble into pack Poor consistency and the cell balance performance is poor after the pack is assembled
The reason for the coexistence of the two in the market lies in the respective adaptability of the two due to the above differences.
